1' To all whom it may concern.-

' Be it known that I, IVORY HAZELTON, a citizen of the United States,residing in the city and county of Philadelphia, State of Penn- '5sylvania, have invented a new and useful'Improvement' in Oar-Couplings,which improvement is fully set forth in the following specification andaccompanying drawings.

- My invention consists of a car-coupling {0 formed of a knuckle whichis pivoted on the draw-bar and a locking device of novel con-- structionfor controlling said knuckle when in coupling position, as'will behereinafter set forth; r Figure 1 represents a perspective view of acar-coupling embodying my invention. 2 represents a. longitudinalvertical section thereof Fig.3represents aperspective view of anotherform thereof. Fig. 4 represents a horizontal section thereof. Similarletters of reference indicate corre sponding parts in the severalfigures.

Referring to the drawings, A- designates a draw-head, and B designates aknuckle which 2 5 is connected therewith by means of the vertical pivotO. The knuckle has an extension or heel D, rearward of its pivot oraxis, movable ina horizontal recess. in the draw-head, and in the saidheelisa vertical slot or groove go E, which isada'pted to receive atongueF, the latter being connected with a horizontally-arranged shaft Gwhich is moii-nted'on the draw-head and provided with a crank-handle II,said draw-head having a shoulder against ;5 which the heel is adapted toab'ut'whenit entors said draw head. I

The operat-i'0n is as follows When the.
